The cyAPI.lib file in FX2LP and FX3

[MaXi_1246331]

Previously I have developed the windows application. It import cyAPI.lib file when linking. Now I developed the FX3 windows application, can I use cyAPI.lib for FX2LP. I compare the cyAPI.lib for FX2LP and FX3 byte by byte, I find differences. Does cyAPI.lib contains implementation or it links to other file in running phase?

Hello,

The CyAPI.LIB is common for FX2LP and FX3. The CY3684 DVK is not being updated to the latest versions of the CyAPI.LIB. The FX3 SDK has the latest versions of the library files. Please use the CyAPI.LIB from the FX3 SDK page.

Thank you. I have further question. Does cyAPI.lib contains implementation or it links to other file containing implementation in running phase? Does the driver mean the inf file? I guess the driver contains implementation.

Hello,

The CyAPI.LIB interacts with the CYUSB3.SYS driver to perform data transfers with the device. The CYUSB3.SYS is the driver file that contains the implementation.
